Title: Improvements in and relating to variable reactance electrical circuits
IPC: H03L7/06
Filed: 1946-02-04
Abstract: 639,980. Automatic frequency control systems. PHILCO PRODUCTS, Inc. Feb. 4, 1946, No. 23593/49. Convention date, Feb. 3, 1945. Divided out of 639,922. [Class 38 (iv)] [Also in Group XL (c)] A variable-reactance valve is operated under Class C conditions and is so associated with a valve oscillator that the frequency is varied by varying the frequency of a control signal applied to the reactance valve. As shown in Fig. 3, a variable-frequency control wave is applied to a control.electrode 10 of a heptode mixer valve 9, and a wave from a local backcoupled oscillator valve 19 is fed to the other control grid 11 of the heptode. The 'anode circuit of the latter includes a damped oscillatory circuit 13 tuned to the centre frequency of the control wave and inductively coupled to the tank circuit 20 of the valve 19. The frequency of the local oscillations depends partly on the tuning of the tank circuit 20 and partly on the strength of the quadrature feedback provided by the coupling 15, 20. When the grid 10 is energized at a centre frequency, the oscillations in the circuit 13 are at a normal value and the local oscillation is also at the centre frequency, the grids 10, 11 being energized in phase quadrature. As the control frequency deviates, the phase relation of the grids is disturbed, the excitation of the circuit 13 increases or decreases, bringing the local oscillation into frequency agreement with the control wave, but with such a phase relation between the voltages on grids 10, 11 as will maintain a suitable degree of quadrature feedback at the coupling 15, 20. The separate local oscillator 19 may be omitted, and the cathode, control grid 11, and screen 28 of the heptode valve 9 may be arranged to produce the local oscillation, Figs. 5 and 6 (not shown). The valve 9 is operated under Class C conditions, so that its anode current is in the form of a series of short pulses, which vary in amplitude according to the phase relation between the grid voltages. The circuit does not respond to amplitude changes in the input wave'. The local oscillator may operate at a sub-harmonic of the control frequency, as in Specification 566,255, [Group XL]. In a modification, Fig. 7, the local oscillator valve 53 has a grid tank circuit 55 back-coupled to a cathode coil 56. A phasing-circuit 61, 62 is connected across the tank circuit and the junction 60 feeds a quadrature voltage to the heptode grid 11, causing a, quadrature feed into the tank circuit 55 which lies in the heptode anode circuit.

Title: Arrangement for measuring the gap of a pair of rolls for a roll stand
IPC: B21B38/10
Filed: 1973-05-18
Abstract: 1391029 Rolling mills VEREINIGTE FLUGTECHNISCHE WERKE-FOKKER GmbH 18 May 1973 [20 May 1972] 23869/73 Heading B3M [Also in Division G1] The gap between two rolls of a rolling mill is measured by providing each roll with a projecting ring on one end, the ring co-operating with an inductive, capacitive, optical or electromechanical sensor to give a position signal. An inductive series 13 is shown in Fig. 2, and comprises an E core 14 carrying two coils L 1 , L 2  and positioned adjacent the ring 11 on the end of roll 10. The sensor is mounted movably on a housing 12, Fig. 3, attached to a fixed frame, and the further sensor 13<SP>1</SP> is likweise mounted to co-operate with the second roll. The housings 12, 12<SP>1</SP> contain electric stepping motors, Figs. 4a, 4b (not shown), geared to the sensors so that the latter can be moved along the vertical axis of Fig. 3. The four coils of the two sensors are connected to an oscillator 20, Fig. 6, via a transformer 21<SP>1</SP>; any displacement of the roll rings from the E cores results in the coils L 1  and L 2  becoming of different inductance which is detected at phase dependent rectifiers 25, 25<SP>1</SP> which give D.C. signals A, B representing the positions of each ring relative to its sensor. The apparatus is initially calibrated by bringing the rolls into contact without a workpiece. The stepping motors then move the sensors until the signals A and B are zero. The signal A-B is then fed to a roll gap controller and one or other of the sensors is moved by its motor through a distance equal to the desired gap, and the controller causes the corresponding roll to move a similar distance. The gap is now set and is maintained in subsequent use.

Abstract: 406,368. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, DOWSETT, H. M., 47, Drayton Gardens, Winchmore Hill, both in London, and CADZOW, R., Ardentinny, Argyllshire. Aug. 26, 1932, No. 23933. [Classes 39 (i) and 40 (v).] All points of an object S are transmitted simultaneously, each as the modulation of a different frequency. Transmitter, Fig. 1. An image of the object is focused by a lens L on a flat photo-electric cathode C. A grid G and a gauze plate A are so angularly arranged that no two points on the cathode are at the same distances from both the other electrodes. A high potential is applied by a battery HTB to the grid and a low potential to the plate, and the electrons are kept moving at right angles to the cathode by a magnetic field. Thus the electrons from each point on the cathode oscillate at a different frequency, which is modulated by the light intensity of the corresponding spot on the object. The modulated frequencies are transmitted by radiators l<1>, l<2>. Receiver, Fig. 2. The received currents are applied to a grid G and plate A arranged similarly with respect to an indirectly heated flat cathode EC as those at the transmitter. Similar bias potentials are also applied, so that each received frequency controls the emission from an appropriate point on the cathode, and an image is produced on a fluorescent screen FC.

Abstract: 337,480. Gray, W. H. Oct. 8, 1928, [Convention date]. Planes, arrangement of; steering, controlling; stopping way. -In an aeroplane of the type having aerofoils pivoted to swing about a transverse axis the aerofoil or aerofoils are connected to a pair of vertical rudders having a common axis, so that the rudders move outwardly and in opposite, directions when the angle of incidence of the aerofoil or aerofoils is increased by the pilot and return to their normal close together position when the aerofoil or aerofoils are returned to the normal angle of incidence. In one form an aerofoil 10, Fig. 1, is pivotally mounted at 19 on vertical members 16, 17 secured to a body 11 and is adapted to be rocked about its pivot by means of levers and links 21, 22 connected to a transverse shaft 25 which is rotated by a worm 23 and worm wheel 24 under the control of the pilot. The shaft 25 may be carried by the members 16. The aerofoil is provided with wing bracing connected to a U-shaped frame 13 which surrounds the body 11 and is connected to front and rear spars 14 of the aerofoil 10. In an application to a biplane the lower wings may be secured to the bottom side members of frame 13. The minimum angle of incidence of the aerofoil 10 may be determined by a stop provided on the side of the gear wheel 24 and arranged to strike a fuselage cross member which carries the bearings for the worm wheel 23. The rudders 3C, 31 are hinged to a common rudder post formed by the rear edge of a fin 33 and project an equal distance above and below divided elevators 34, 34<a>. Rudder levers 30a, 31a are connected by cables 36, 36a to the forward ends of the levers 21 so that the rudders are moved outwardly when the aerofoil 10 is moved from its normal position to an increased angle of incidence. Non-automatic control of the rudders is effected by pedals, 38, 38<a>, Fig. 5, to which ara connected short cables 44 joined at Z to the cables 36, 36<a>. Since these connections 44 become slackened and hence inoperative when the aerofoil 10 is tilted and the cables 36 rendered taut by their connection to the levers 21, arms 42 having eyelets 43 through which are passed the cables 36 are provided on the pedals thus enabling an additional movement to be given to either rudder cable beyond that caused automatically; this is indicated by the dotted line of Fig. 5. Landing wheels. - The undercarriage may be secured to the frame 13 and be tilted therewith.
